When it comes to Bluetooth speakers, small is hot. We have Jawbone and all the marketing it put behind its Jambox partially to thank for that. With its rechargeable battery and impressive sound for its size, the Jambox showed how you could take a tiny portable speaker and pair it with your smartphone, tablet, or laptop to create a mini wireless stereo system just about anywhere you were.

But some folks don't want to drop $150 to $175 on a portable speaker, which is why I've put together this list of less expensive alternatives. We'll be reviewing more inexpensive portable Bluetooth speakers as the year goes along and we'll continue to update this list as we listen to new products and earlier models we might have missed.

The iDM11 sells for a modest $70 and also has speakerphone functionality.
